To alt whom it rmty cancer-rt." v

Be it known that I, BUHNHAM 3. Brion- NEY, a citizen of the UnitedStates, and a resident of the city of Elisabeth, county of Union, andStateof New Jersey, have invented certain new and useful improvements inlype- Writing Machines, of which the following is a specification.

This invention relates, rimarily, to typewriting machines in whichradially-disposed type bars are arranged about a common prii'itingqniintand lnove'one at a time to the printing, position. These typebars, especially in lrimtsstrike machines, are often closely arranged, so that inrapid operation there is liability of clashing, due largely to the factthat the type-bars are apt to rebound from the basket or cushion uponreturning to normal position, thus getting; into thepath of asubsequently-operated type bar.

The principal object of my invention, therefore, is to minimize theliability of the typebars to rebound in this manner.

In the drawings forming part of this specification, and in which likesigns-denote like parts, Figure 1 is a'sectional elevation of atype-bar, typebasl ;et, and platen of an unturning the figurequarter-way around itwil be seen that it rep resents like parts in afront-strikamachine in which the,type-bars lie horizontally and belowthe plane of the printing-point. Fig. 2 is a plan of the type-basket orring seen at .lllg. l, the type-bars being indicated in crosssection.

A radial series of type-bars 1, carrying typesZ, which. strike against aplaten 3, is

supported by hangers 4 upon a ring, so inent, or plate 5 and operated bymeans of pu l-rods 6 or otherwise and usually provided withreturning-springs The type bars normall re t in contact at their typeends with a flexibl ring or as mcnt, consisting of a casing 14 of somefiexi. ility and preferably tough and inelastic, filled with sand orother forcoabsorbing material 15, althou him some cases the casing neednot be entire y filled by the material.

The device may be supported in any suitable way, preferably uponinturned fingers 9, formed at the lower edge of a thin still sheet metalring or band 10, the latter being hung may possibly drive s upon rods11, attached to the top plate 5 or otherwise supported. in front-strikeIna. chines the member 10 may be in the form of a segment and in somecases may be omitted.

The device being flexible yields more or at the impacts ol'' thetype-bars, and owing to this yielding movement some of the adjacent andopposite type-bars are jarred,

thereby taking up much of the-force of the blow and minimizing thereaction of the parts, so that it does not tend to throw the type barback with. force, the tendency of the same to rebound being lessened,While owing to the inelastic character of the filling the force of theoriginal blow of the type-bar is still further absorbed, particularlybecause the filling is incased in'soit inelastic material, so that thebar u ion striking the basket lightly past its normal position, but willnot rebound to the extent of causing it to clash with asubsequentlyoperated type-bar. This enables the operation oi the machineat high speed without den or from this source.

'1 e curved frame or ring 10 is substantial and protects the cushionfrom injury. It also prevents undue displacement of the cushion.Preferably a narrow space is left at 12 between the ring or segment 10and the inner member, so as to allow slight-headers. of movement of thelatter. Durin, such movementi there may be more or less .riotion betweenthe cushion and the fingers or shelves 9 whereon it is so ported,thereby further tending to absorb tie force of the type bar ows.

lhe filled or partly filled casing 14 is head ble and inelastic,rendering it desirable for a type-basket, either with or without thestill rmrror segment 10.

Variations may be resorted to within the scope of my invention, andportions of in r improvements may be used without other Having thusdescribed my invention, *5. Cl9,iIt'-- 1. In a type-writing nation witha series r" therefor consisting o fined within a satin rial.
